Morini, Stretch, Nuvinci 8sp, SBP in progress

This is a work in progress. I will post more about it later with more pictures.

07/23/09 The engine is a 49.8CC 3.2HP and it is upgradable to 5.8HP. I only have about 30 miles on it and most of them test runs. It seems as strong or stronger than my HT engine. My speedometer read 42mph when i opened it up recently. This is the same as the HT engine but the Morini isn't broken in yet. The Morini has some vibration at midrange but smooth at high rpm. Some of it may be the clutch and I hope it gets better. It is barely audible when idling compared to the HT. The pipe I have is loud (for me) but I'm working on it. I included a picture of my rear motor mount/jackshaft combination. It also holds the idler for the jackshaft to crank chain.

The rear hub is a Shimano Nexus 8 speed with a roller brake added. It is rated for offroad use and has about 400 motorbike miles on it with no problems. I JUST NOTICED THE NUVINCI IN THE TITLE. MUST HAVE PUT THAT THERE SUBCONSCIOUSLY. IT IS A SHIMANO NEXUS.

this looks like the perfect ride to me!!! can you tell us about the mounts for the motor and shift kit and maybe some close up shots? is this a 50cc morini? and is there a rear brake on the nuvinci hub?

WOW, that IS Cool!!!

I'm just gonna have to step up to the plate and get a Morini
fitted to one of my frames. I absolutely love the kickstart.

Man, get a helmet!
With that Morini & Nuvinci you'll be reaching speeds of 55+...!

Good Job!

the chain set up looks very professional . Could we see more pics of that ? are you running some kind of electric start ?

No electric start. Only the kick start on this engine. Here are more pictures of the mounts.

Good work. Did you make the jack shaft set up for it?

Thank you, I made the jackshaft itself from a kit. You get the bearing holders which look like big washers and a 5/8 shaft. The crank and freewheel are from Sick Bike Parts.
